The New Fifth Edition of Manual N® details the load calculation procedure that addresses the advances in the commercial construction industry: new materials, methods of assembly, and operational requirements. It provides instruction to help contractors and designers satisfy new, and often conflicting, energy, ventilation, and comfort requirements. The new Manual N is divided into four sections providing both a quick and comprehensive procedure for commercial load calculation.

• Section 1 Abridged Procedure: Basic instructions to perform commercial load calculations, on buildings of three stories or less. Supports a simplified hand calculation.
• Section 2 Advanced Topics: Provides enhanced procedures, capabilities, and sensitivities (requires computer software to process).
• Section 3 Tables: Provides input for the worksheets and determinations needed for the abridged (N5ae) and full (N5) procedures.
• Section 4 Appendices: Provides supporting materials and details on the N5ae and N5 applications...(640 pages)

Important changes in the 2021 IMC include:

• Clothes dryer exhaust terminals required to be at least 3 feet from any opening into a building.
• Polyurethane spray-applied foam on the exterior of ducts in attics and crawl spaces required to meet specific smoke and flame index limits.
• Fire and smoke dampers must be provided with approved access for inspection and maintenance.
• Refrigerant tables updated to include new refrigerants.
• Addition of condensate termination identification markings and discharge restrictions.
• Approved factory-built combination intake/exhaust terminations permitted, relaxing separation requirement.
• 30% reduction in minimum mechanical ventilation for whole-house balanced ventilation systems.
• Continuous operation requirement for manicure and pedicure station exhaust systems.
• Grease duct horizontal cleanout required within 3 feet of a horizontal discharge fan.

NFPA 31, Standard for the Installation of Oil-Burning Equipment is the benchmark for the correct installation of boilers, air heaters, and other liquid fuel-burning equipment, and their fuel supplies. Designers, contractors, and installers rely on this Standard for guidance that protects property and building occupants by ensuring a fire-safe installation.

From carbon monoxide poisoning to the risks of fire and explosion, there are many hazards inherent with the utilization of gaseous fuels. NFPA 54 offers comprehensive provisions for the safe design, installation, operation, maintenance, purging, and inspection of gas piping, equipment, accessories, and appliances supplied with fuel gas.

Updated through January 2023, the book provides a comprehensive set of the most up-to-date Construction regulations. Utilizing MANCOMM’s signature formatting approach – RegLogic – this edition includes notations for changes within the past year and letters of reference.

This book features:

• 1903 – Inspections, Citations, and Penalties
• Part 1904 – Recording and Reporting Occupational Illnesses and Injuries
• Selected 1910 General Industry Standards
• OSHA Forms 300
• Sharps Injury Log
• This edition also includes Subpart AA - Confined Spaces

Modern Refrigeration and Air Conditioning, 22nd Edition is focused on closing the gap from students to technicians with our commitment to top-quality coverage of fundamentals and the latest technology. This classic is an excellent blend of theory, skill development, and service techniques to help you learn how to install and service refrigeration and HVAC systems.

Uses:

• Sizes metal ducts, lined metal ducts duct board airways, and wire helix flexible ducts.
• Converts round shapes to equivalent rectangles.
• Correlates available pressure with total effective length and friction rate (Manual D sizing calculations).
• Converts velocity into velocity pressure and vice versa.
• Corrects for altitude and temperature

Building on a history of duct construction standards nearly 100 years old, the flagship SMACNA HVAC Duct Construction Standard – Metal & Flexible 4th edition represents the state of the art in the sheet metal duct fabrication and installation requirements. Significant changes for the 4th edition include; flat oval tables for positive/negative pressure applications; spray and aerosolized duct sealants; non-fiberglass duct liner applications; added information on spiral duct fittings; updates to duct hanger requirements; flexible duct hanger spacing and support bracing.

NFPA 58: Liquefied Petroleum Gas Code provides minimum safety requirements for all liquefied petroleum gas (propane) installations, from small cylinders installed at residences to large bulk storage facilities that can exceed 100,000 gallons. The code includes minimum requirements for safe handling during LP gas transfer, including operator qualifications, maximum filling quantity in containers, and pre-transfer inspections to ensure containers are fit for continued service.

This standard is the industry benchmark for helping safeguard personnel and facilities from risks of fire and explosions during pipe system maintenance. From notifying and training personnel involved in cleaning and purging operations to identifying a safe discharge point and preventing the development of a flammable gas mixture in occupied areas, NFPA 56 provides information and requirements that everyone at your facility can apply to better avoid incidents and help protect lives and property.

From simple applications to multi-load and multi-temperature systems, this one-of-a-kind, comprehensive text prepares readers to use the latest hydronics to create systems that deliver the ultimate in comfort, reliability and energy efficiency. Abundantly illustrated with product and installation photos and hundreds of detailed, full-color schematics, MODERN HYDRONIC HEATING, Fourth Edition, transforms engineering-level design information into practical applications useful for technical students and heating professionals alike. The revised edition features the latest design and installation techniques for residential and light commercial hydronic systems, including use of renewable energy heat sources such as air-to-water and geothermal heat pumps, hydraulic separation, variable speed circulators, distribution efficiency, heat exchangers, buffer tanks, heat metering, hydronic cooling, system balancing and proper system documentation. Anyone involved in the heating trade will benefit from this preeminent resource of the North American heating industry, which is equally well-suited for formal education courses, self-study or on-the-job reference.

Now in its third edition, the book has been fully updated to incorporate the latest technological advancements, with an all-new chapter on boilers, and updated chapters on electrical equipment and oil burner controls. With coverage of the combustion process, oil burners, heating systems, as well as electrical systems and equipment, users will build a solid foundation of information that is easily transferable to work situations they may encounter in the field. Straightforward and easy-to-use, this book is a valuable addition to every service technician’s vehicle or learning library.
